Patent applications made for PRISMS technology

Transcend Engineering has confirmed it has filed US non-provisional patent applications related to its Profile Resolving In Situ Soil Moisture Sensor (PRISMS) technology. PRISMS uses time domain reflectometry (TDR) to resolve spatially continuous variation in soil moisture over depth, providing high-resolution monitoring of spatiotemporal trends in soil moisture distribution.

The ability to acquire time series measurements of in situ soil moisture in continuous profile has long been sought for use in waste site remediation, civil infrastructure health surveillance, early warning of landslide potential, climate-related land-atmosphere interactions, and improved irrigation management and water conservation. The technology can also be applied to permafrost monitoring, and moisture distributions in stored grain and other media.

Prototype PRISMS sensors have been deployed at the U.S. DOE Sustainable Systems Scientific Focus Area (SFA) 2.0 site in Rifle, CO, and in the Tropical Response to Altered Climate Experiment (TRACE) in Luquillo Experimental Forest, Puerto Rico.

Transcend Engineering has received funding to develop PRISMS from the U.S. Department of Energy’s Office of Science through a Small Business Innovation Research (SBIR) grant. Work under the Phase 2 SBIR award began in April 2014.

Transcend Engineering develops innovative sensors and instrumentation for geotechnical, oceanographic, atmospheric, transportation, and security uses.
